Background technique
In the design process of ray machine detection system, usually need for optical device provides accurate rotation; Conventional optical device comprises optical polarizer, and optical lens group installs wheel, optically filtering assembly, and optical compensator etc.In order to obtain desirable optically detecting resolution, designing and having low or Zero-drive Chain play, the rotating machinery of high transmission accuracy and endless operating life is very important.For the optical device worked under the laser beam, if driving mechanism produces contamination particle in rotation process, these particles will rest between kinematic pair, as gear pair or cam pair etc.; It will produce size error on rotating device, and it will affect the transmission accuracy of mechanism.If this driving mechanism needs to smear oiling agent on the driving part, oiling agent will produce at surface optical device and pollute, and this will reduce the service behaviour of optical device greatly.Therefore, have both without particle contamination in the urgent need to one, also the unlubricated dose of optical device driving mechanism polluted.Up to the present, typical optical device rotating mechanism still uses gear pair, chain wheel pair, cable drive and actuated by cams etc.All respective shortcoming and defect is there is in these driving mode in the application of ray machine detection system.
In traditional rotating drive mechanism, gear drive is widely used.Based on the mechanical property of its driving principle, gear can produce the meshing error of between cog.Play between gear pair is inevitable, even if use clearance elimination gear.Therefore the backlash between gear affects its transmission accuracy greatly.In addition, due to the existence of the mating surface frictional force of gear pair, it will produce fine particle around working environment, and the meeting that they have rests on gear surface becomes the another error source affecting Bite size precision.In order to the lubricant oil or other oiling agents that reduce gear tooth friction use can become again the another pollution sources affecting surface optical device turbidity test.The friction of gear surface can cause wearing and tearing to the flank of tooth simultaneously, and then affects working life.Consider above-mentioned shortcoming and problem, can say that gear pair transmission is not desirable for ray machine detection system method for driving.Worm gear pair transmission is a special case of gear pair transmission, and it and gear pair transmission above-mentioned have similar shortcoming and problem, therefore also inapplicable.
Toothed belt and belt wheel mechanism, chain and sprocket mechanism is also the conventional method for rotary actuation.Although toothed belt and belt wheel have relative little play, this kind of transmission has friction easily to produce contamination particle equally.These particles are also easily fallen on surface optical device, and this will make optical device service behaviour worse and worse.Most toothed belt material is also not suitable for the working environment of this type of optical device, because this working environment is usually exposed in laser beam, even under ultraviolet and DUV.As for chain and sprocket transmission, due to the size of chain and sprocket wheel and non-critical control, and chain tension also can change along with the increase of running time, and these characteristics make its transmission play very large, and its transmission process also can produce particle contamination.These characteristics make chain and chain-wheel mechanism also cannot adapt to and ray machine detection system, because this system requirements high rotation precision, without particle contamination, and operating life wants long enough.
Actuated by cams is a kind of special mechanism utilizing frictional force to drive, and transform linear motion can be rotary motion by it, it need rely on cam and cam is attached take turns between frictional force realize drive, therefore this driving process be also easy to produce microparticle.Usually need to provide lubrication to cam, this affects the pollution sources of optical device performance by becoming.
Electric cable rotary drives and is applied to different fields.If select the cable material of high strength, this kind of driving has low or zero particle contamination, relatively low or zero drive play.But because the cable of this special material is expensive, because which limit its application.

When concrete layout, band and pulley have two kinds of coiled fashion, and a kind of setting being band 1 and band 22 and being in same plane, when namely when described band one and band two, the projection on pulley one a and pulley two b external common tangent plane overlaps; Another kind is the setting that band 1 and band 22 are in Different Plane, namely when described band one is parallel with the projection of band two on the outer tangent plane of pulley one a and pulley two b.Two kinds of coiled fashion all need to guarantee band and self do not overlap, and therefore need to limit respectively two kinds of embodiments.
In addition, owing to there is the relation being greater than, being equal to or less than between pulley one a and the diameter of pulley two b, conveniently follow-up description, to this specification hereinafter all the elements, all limit pulley one a diameter and be less than or equal to pulley two b.
First embodiment:
As depicted in figs. 1 and 2, the schematic diagram in same plane is in for band one of the present invention and band two, namely when when described band one and band two, the projection on pulley one a and pulley two b external common tangent plane overlaps, as seen from the figure, described band one and band two must limit described band 1 and the tie point of band 22 on pulley one a and pulley two b and all be positioned on two arc surfaces in the outer part that pulley one a and b and its two outside common tangents form, on two arc surfaces in the outer part that namely position of mounting groove is arranged on pulley one and between pulley two and pulley one and two, two outside common tangents are formed.The object of such setting is because if tie point is positioned on arc surface in the inner part, will inevitably overlap and interfere between two bands, therefore can only be arranged on outer arc face.Now the rotating range of pulley depends on a band shorter in band 1 and band 22.
Further, as shown in Figure 3, for be with 1 and band 22 be in same plane, band one is equal with band two length, and band one and the situation of being with two two end part tie points to contact.In this case the slewing area of pulley one a and pulley two b is maximum.
Further, Fig. 4 is the mode of execution of Fig. 3 illustrated embodiment when pulley one a and pulley two b equal diameters.In pulley one a and b equal diameters (i.e. velocity ratio 1:1), band 1 is equal with band 22 length and band 1 reaches maximum angle of swing 180 ° with when being with 22 two end part tie points to contact.
Further, the situation of Fig. 3 and Fig. 4 can also be an endless belt being set on pulley one and pulley two, described band and pulley one and pulley two are respectively arranged with fixed connection point, and described band 1 and band 22 are the part of described band between these two fixed connection points.
Therefore, when the first example belt one and band two are in same plane, the accessible maximum rotation scope of pulley is 180 °.Visible its be less than 360 ° therefore in this set band one and band two can not overlap with self and can not interfere.
Second embodiment:
If Fig. 5 with Fig. 6 is that band one as described in the present invention works as (is with one 1 to be in setting in Different Plane with band 2 2) with band two when pulley one a is parallel with the projection on pulley two b external common tangent plane, and with the schematic diagram that one 1 and band 22 are arranged along pulley one a and pulley two b outside common tangent, as seen from the figure when band 1 and band 22 are in Different Plane, be with one 1 can not interfere each other or overlap with band 22, therefore must limit band on pulley one a and pulley two b, to coil maximum magnitude be no more than one week, namely be with 1 and the length of band 22 all need to be less than pulley one a and pulley two b outside common tangent length and pulley one a and pulley two b girth sum, otherwise band will overlap with self, and then change diameter of pulley, affect transmission accuracy.
Further, the fixed position that limit the two end part of band 1 and band 22 must ensure that at least pulley is with one all not overlap with self with band two in certain rotating range.If do not carry out such restriction, then likely to occur in Figure 22 thus situation, the position relationship that band one in figure and the tie point of band two are arranged, outside common tangent point of contact on the upside of pulley one a is positioned at a tie point be positioned on pulley one a, now be with one 1 on pulley one a, coiled one week, outside common tangent point of contact place on the downside of pulley two b is positioned at two tie points on pulley two b, and only have this point to contact with pulley two b, therefore pulley a and b now can only be rotated clockwise, and owing to being with one 1 to coil one week at pulley one a, now will inevitably cause band 1 and overlapping itself.Pulley is caused just to be with a situation that will overlap with self once rotate.Therefore at least pulley is with one all not overlap with self with band two in certain rotating range to need the fixed position at the two end part limiting band 1 and band 22 to ensure.
Further, as shown in Figure 7, in this kind of coiled fashion when, be with 1 and band 22 length equal pulley one a and pulley two b outside common tangent and pulley one a girth sum, one end with one and pulley two b (or pulley one a) is fixedly connected with at outside common tangent point of contact, upside, the other end with this point of contact for starting point along upside outside common tangent extend to pulley one a (or pulley two b) and coiling arrange; One end of described band two and pulley one a (or pulley two b) is fixedly connected with at outside common tangent point of contact, downside, the other end with this point of contact for starting point along downside outside common tangent extend to pulley two b (or pulley one a) and on coil setting.Pulley one a and pulley two b has maximum rotation scope.

3rd embodiment:
If Fig. 9 with Figure 10 is that band one as described in the present invention works as (is with one 1 to be in setting in Different Plane with band 2 2) with band two when pulley one a is parallel with the projection on pulley two b external common tangent plane, and with the schematic diagram that one 1 and band 22 are arranged along pulley one a and pulley two b internal common tangent, as seen from the figure when band 1 and band 22 are in Different Plane, be with one 1 can not interfere each other with band 22, therefore must limit band on pulley one a and pulley two b, to coil maximum magnitude be no more than one week, namely be with 1 and the length of band 22 all need to be less than pulley one a and pulley two b internal common tangent and pulley one a and pulley two b girth sum.
Further, identical with the reason of the second embodiment, the fixed position that limit the two end part of band 1 and band 22 must ensure that at least pulley is with one all not overlap with self with band two in certain rotating range.
Further, as shown in figure 11, in this kind of coiled fashion when, be with 1 and band 22 length equal pulley one a and pulley two b internal common tangent and pulley one a girth sum, one end with one is fixedly connected with outside common tangent point of contact on the upside of pulley two b, and the other end extends to pulley one a for starting point along upside outside common tangent with this point of contact and coils setting; One end of described band two is fixedly connected with outside common tangent point of contact on the upside of pulley one a, the other end with this point of contact for starting point along downside outside common tangent extend to pulley two b and on coil setting.Pulley one a and pulley two b has maximum rotation scope.
Further, as shown in figure 12, in above-mentioned this coiled fashion, as pulley one a and pulley two b equal diameters (i.e. velocity ratio 1:1), now pulley one a and pulley two b has maximum rotation scope 360 °.
As can be seen here, when band 1 is parallel with the projection of band 22 on the outer tangent plane of pulley one a and pulley two b (band 1 and band 22 are in Different Plane and arrange), be with one 1 can not interfere each other with band 22, therefore must limit band on pulley one a and pulley two b, to coil maximum magnitude be no more than one week, namely be with one 1 and be with the length of 22 all to need to be less than pulley one a and pulley two b outside common tangent and pulley one a and pulley two b girth sum.When pulley one a and pulley two b equal diameters (i.e. velocity ratio 1:1) in this kind of coiled fashion, be with 1 and band 22 length equal pulley one a and pulley two b outside common tangent (or internal common tangent) length and pulley one a girth sum, and with 1 and the two end part link position of band 22 according to following setting: namely described band 1 and the band 22 ends tie point on pulley one a and pulley two b meet when band 1 end pulley one a (or pulley two b) on tie point be in this pulley outside common tangent cusp position and band 1 only has this end to contact with this pulley time, described band 22 pulley two b (or pulley one a) on also only have end attachment to contact with this pulley and described tie point is in this pulley outside common tangent cusp position time.Or described band 1 and the band 22 ends tie point on pulley one ab meet when band 1 end pulley one a (or pulley two b) on tie point be in this pulley internal common tangent cusp position and band 1 only has this end to contact with this pulley time, described band 22 pulley two b (or pulley one a) on also only have end attachment to contact with this pulley and described tie point is in this pulley internal common tangent cusp position time.There is maximum rotating range 360 °.Namely rotating range is not more than one week, and therefore in this set, band can not overlap with self and can not interfere.
When being in Different Plane owing to being with 1 with band 22, maximum rotating range 360 ° can be realized, therefore the present invention take this setup as the preferred embodiment of the invention, further, due to band 1 and band 22 are arranged more easy according to pulley one a and pulley two b outside common tangent, therefore be the preferred embodiments of the present invention with this setup, below preferred embodiment (Figure 13) be further described.
If Figure 13 is the three-dimensional assembled view of the present embodiment when having maximum rotating range (360 °).Wherein pulley one a of visible two same sizes and pulley two b, wherein drives the concrete needs of optical instrument, pulley two b is set to ring-type according to pulley two b.Pulley one a is driven by motor 4 and provides driving moment to tape handler.Therefore pulley one a is driving wheel, and pulley two b is driven wheel.The velocity ratio of this driving mechanism is 1:1.Optical component is installed on pulley two b, and together rotates with pulley two b.When motor drive pulley one a is rotated counterclockwise, pulling force passes to pulley two b by band 1 above, and therefore pulley two b drives the optical device be arranged on above it to turn an angle, and this angle can have 0 °-360 °.Band 22 is below entourage, and it can not provide driving force.When in the process of turning clockwise, band 22 below will transmit pulling force for pulley 2, and band 1 above becomes entourage again.Because rotary motion is produced by logical pulling force, do not rub between the belt and the pulley, in this rotary course, do not produce wear particle, band and pulley all can not produce wearing and tearing.Owing to producing wearing and tearing, use this tape handler, can not produce at optical-mechanical system and pollute, the surface of optical device can keep clean, and therefore the performance of optical device can be guaranteed for a long time.
For the material making pulley one a and pulley two b, owing to considering that tape handler of the present invention can not produce wearing and tearing, the material therefore making pulley can adopt aluminium (other possible materials).Because aluminium low price is convenient to again processing.
As Figure 15 be in the present invention with structural representation.The material of band should be the free of contamination material of a kind of high strength.Need to guarantee that enough intensity is not easy to be extended stretching (demand of highi degree of accuracy underneath drive error) again there is elasticity simultaneously, be easy to bending deflection (demand of coiling on pulley) specifically.Therefore consider that use is called the alloy of " ELGILOY ".I.e. Elgiloy (ELGILOY).This alloy resulted from for the 1940's, produced in wrist-watch industry at that time to the needs of mainspring of watch.ELGILOY is a kind of, cobalt Co, chromium Cr, the alloy of nickel etc.Wherein at least comprise Co, Cr, Ni, Mo, Mn.Preferably its component ratio is: Co40%, Cr20%, Ni 15%, Mo7%, Mn2% etc.Through heat treatment process, the strip made by this material has very high intensity.And this kind of material can not produce any pollutant.There is again very high fatigue strength simultaneously, therefore use this material can obtain the operating life of endless.Except this ELGILOY material, stainless steel material is also the material being well applied to this tape handler, therefore with material also can adopt stainless steel.The bending radius of band, the thickness of band and width selected, all should determine according to the result of the concrete Stress calculation of this tape handler.
Described band 1 and band 22 can be connected directly between the outer surface of pulley with pulley one a and pulley two b, and specifically can adopt the modes such as bonding welding, in order to ensure the level and smooth of pulley surface, therefore the thickness of tie point is little as far as possible, close to the thickness of band.Apparently higher than pulley surface, can be unfavorable for that driving mechanism runs according to devices such as briquetting screws.
Therefore consider the height reducing tie point, can also also arrange mounting groove 22 at described pulley one a and pulley two b outer circumferential face, described band 1 is arranged on described mounting groove 22 internal fixtion with band 22 ends and is connected.Arranging tie point is like this positioned under pulley surface, farthest reduces tie point height to the impact of tape handler.
